Went on the tour on a Sunday, so fun. Got to see the band walk the guard home from Westminster Palace. What a bonus. The trip was definitely one of our weeks highlights. Super family friendly, bikes were easy to ride and our guide, Xenia was awesome. Fun spirit and great tidbits about the city and its history. The pub was welcoming and beers were great and the public art experience (graffiti art) was a unique experience for all four of us.
